1. AN APPARATUS FOR MEASURING THE TRANSVERSE DIMENSION OF AN OBJECT SUCH AS A WIRE, CABLE, TUBE OR TAPE, WHICH COMPRISES AN EMITTER OF RADIANT FLUX, A DIAPHRAGM LIMITING SAID FLUX, A PHOTOELECTRIC RECEIVER OF THE RADIANT FLUX PASSING THROUGH THE FIELD OCCUPIED BY SAID OBJECT AND THROUGH SAID DIAPHRAGM, A MODULATING MEMBER LOCATED IN THE FLUX PATH FROM SAID SOURCE TO SAID PHOTOELECTRIC RECEIVER, SAID MODULATING MEMBER COMPRISING A SURFACE ALSO RECEIVING SAID RADIANT FLUX, SAID SURFACE COMPRISING A SERIES OF CONTIGUOUS ZONES WHICH ARE ALTERNATELY OPAQUE AND TRANSPARENT TO SAID FLUX AND ARE BOUNDED BY SHARP LINES OF DEMARCATION BETWEEN SUCCESSIVE ZONES, SAID SERIES OF ZONES HAVING SELECTED PITCH MEASURED BETWEEN CORRESPONDING BOUNDARY LINES OF LIKE ZONES, AN OPTICAL SYSTEM PROJECTING AN IMAGE OF SAID OBJECT ON SAID SURFACE OF SAID MODULATING MEMBER SO THAT SAID IMAGE AND SAID SURFACE LIE IN CONJUGATE OPTICAL PLANES WITH THE TRANSVERSE DIMENSION OF SAID IMAGE EXTENDING CROSSWISE OF SAID ZONES, MEANS FOR PRODUCING RELATIVE PERIODIC MOVEMENT BETWEEN SAID IMAGE AND SAID MODULATING MEMBER DURING A SCANNING CYCLE, SAID MOVEMENT BEING IN A DIRECTION CROSSWISE OF SAID ZONES, SAID MODULATING MEANS AND OPTICAL SYSTEM COOPERATING WITH ONE ANOTHER TO VARY THE RELATION BETWEEN THE PITCH OF SAID ZONES AND THE WIDTH OF SAID IMAGE TO CAUSE THE WIDTH OF SAID IMAGE TO BE APPROXIMATELY EQUAL TO THE PITCH OF A ZONE, SAID PHOTOELECTRIC RECEIVER SENSING THE RADIATION PASSING THROUGH SAID DIAPHRAGM AND PAST SAID OBJECT AND MODULATING MEMBER TO PRODUCE A PHOTOELECTRIC SIGNAL CORRESPONDING TO THE RADIATION RECEIVED BY SAID RECEIVER, SAID SIGNAL PASSING THROUGH A POINT OF MINIMUM CHANGE WHEN THE PITCH OF SAID ZONE IS APPROXIMATELY EQUAL TO THE WIDTH OF SAID IMAGE, AN ELECTRICAL CIRCUIT INCLUDING SAID PHOTOELECTRIC RECEIVER AND MEANS FOR MEASURING SAID PHOTOELECTRIC SIGNAL AND MEANS TO INDICATE THE POINT AT WHICH SAID APPROXIMATE EQUALIZATION OF THE PITCH OF SAID ZONE AND IMAGE WIDTH OCCURS AND THEREBY INDICATE THE VALUE OF SAID TRANSVERSE DIMENSION OF SAID OBJECT.
